Dwight,
If you have prior welding experience, I'm surprised you're having trouble making a nice looking bead with the wire welder. You may already know this, but make sure you're using the correct polarity for the wire you're using. I'm assuming you're using flux-core wire since I don't see a shielding gas bottle in the pictures. The leads have to be reversed inside the welder to switch from solid core to flux core. You can weld using the wrong polarity, but it makes a pretty ugly bead.
